We study by stepwise regression method, the influence which atmospheric pollution in Jilin City has on the rate of death accorrding to cancer. The extremes are discovered and we know that $SO_2$ and smoking are important factors too.

The degree of atmospheric pollution from automobile engine exhausts has been measured at 1-ga, Eulchiro, Jung-ku, one of the heaviest traffic junctions in Seoul. By determining the concentrations of Pb, $SO_2, NO_2, NO, CO \;and\; CO_2$ in atmospheric air measured are as follows: Pb, $21{\sim}2 {\mu]g./m^3.;\;SO_2,\;0.33{\sim}0.001\;ppm.;\;NO_2,$ $0.20{\sim}< 0.01\;ppm.;\;NO,\;1.30{\sim}0.02\;ppm.;\;CO,\;40{\sim}<\;5ppm$.; and $CO_2,\;0.040{\sim}0.034%$. The mean concentrations determined are as follows: Pb, $11 {\mu}g./m^3.; SO_2, 0.08 ppm.; NO_2,$ 0.09 ppm.; NO, 0.37 ppm.; CO, 16 ppm. and $CO_2,$ 0.038%. Generally, the concentrations of Pb, $NO_2, NO, CO\; and\; CO_2$ are approximately proportional to the traffic density, vehicles passing per hour.

This Study shows the effect of the district heating on the $SO_2$ concentration reduction. In order to analyze the effect of the district heating, three alternatives were set up as follows; Alternative I represented present central heating system, and Alternative II and Alternative III represented district heating system of which the scale were different from. The concludions of this study are as follows; In case of the Alternative II and III, annual average $SO_2$ concentration are reduced by 9.0% and 14.6% respectively, and winter season $SO_2$ concentrations are reduced by 12.2% and 15.8% respectively, at the highest points. The average reduction rates of $SO_2$ concentration in the district heating area are about the same as the reduction rates at the highest points. Also, it was found that using the district heating system, the ground level $SO_2$ concentrations could be reduced within the area of 5 to 10 km radius.

The Characteristics of atmospheric flow and dispersion of air pollutants in the mountainous coastal area were studied using two-dimensional model by the combination of land-sea breezes and transport. The pollutants emitted into the simulated wind field in considering with the mesoscale local circulations. The typical effects of land-sea breezes and tophography of coastal area on the dispersion are discussed in detail, and the model is proved as an useful tool to pridict real time pollutant transport by the results of application studies in Pusan, Korea where the urbanized coastal area with mountainous topography. It was found that sulfur dioxide ($SO_2$) are differently transported and concentrated as going inland by the influence of the sea breeze with topographic changes. Key words : land-sea breezes, sulfur dioxide, dispersion, coastal area.

This study quantified $CO_2$, $SO_2$ and $NO_2$ uptake by vegetation in Seoul. The natural area was only 20% of the area of Seoul and its tree-age structure was dominated by a young and growing tree population. However the natural area accounted for about 65%, 60%, and 59% of total $CO_2$, $SO_2$ and $NO_2$ uptake relatively. In natural area broad-leaved forest was dominative and accounted for about 37.8%, 36.7%, 36.6% of total $CO_2$, $SO_2$ and $NO_2$ uptake in Seoul relatively. In urbanized area the park type land use played an important role. It's area was only 17% of the urbanized area in Seoul, but it accounted for about 67%, 57%, and 56% of $CO_2$, $SO_2$ and $NO_2$ uptake in urbanized area relatively. Total annual uptake by vegetative cover was estimated as 446,741 ton/yr for $CO_2$, 314 ton/yr for $SO_2$ and 815 ton/yr for $NO_2$, and economic value of atmospheric purification for the entire area of Seoul amounted to approximately \228,073 millions/yr for the annual $CO_2$, $SO_2$ and $NO_2$ uptake. The results from this study are expected to be useful not merely in informing the public of atmospheric purification values of vegetative cover, but in urging the necessity for replanting and management budgets.
